Abstract (en)

[origin: EP0622132A1] Device for forming a special steel diaphragm for vacuum insulation elements in a press which has a bottom plate (1) that accepts a pressing pressure and a cover plate (12) which can be moved towards the said bottom plate and exerts pressing pressure, a rubber pad (5) which diverts the pressing forces in directions transverse to the direction of motion of the cover plate (12) being provided adjacent to a blank (3) to be formed. Method for forming special steel diaphragms in a press provided with a bottom plate (1) and a cover plate (12) which can be moved towards the said bottom plate and exerts pressing forces, the pressing forces exerted by the press ram (2) being diverted in directions transverse to the directions of motion of the press ram (2) by means of a rubber pad (5). <IMAGE>
